Have had this for about a month and a half now, charge is extremely quick when plugged into AC. Charges decently fast when hooked up to solar, I have a combined 720 watt input. So far everything seems to be operating correctly, I did have one issue where it dropped its Wi-Fi connection and I kind of had an issue getting it reestablished. I reached out the service and they gave me some ideas of how to get it to work again, I got it to work again. I do have two extra smart batteries attached to this Delta 2 Max. With everything hooked up it does take quite some time to charge on solar. Which is to be expected though it has to feel quite a lot of power reserve. This will come in handy when the power goes out and I need to maintain critical items in my home. All in all I think it's probably a great product, only time will tell though.

I have the Delta 2 Max and 2 extra batteries. I really like the options in the app from being able to limit charge rate and AC always on, and much more. One extra battery fits nicely on top of the Delta 2 Max, but the Dela 2 Max does not fit snug on an extra battery, I wish it did. Overall I recommend. It does not take the place of a true UPS, but I already had a UPS anyway. My only complaint so far is one of the extra batteries came with a bad display, but I guess I'll keep it. I don't want the hassle of a return and I use the app anyway.

I had just received my Delta 2 Max (D2M) a week before we had an unexpected and unexplained power outage. It was right at dinner time as food was going into the oven. Fortunately I had the D2M at the ready and routed a 20-amp power cord from the D2M to my transfer switch. We were able to run the 1700 watt toaster oven for approximately 45 minutes along with lights, computer, a refrigerator, and a freezer. This drained the battery in the D2M to about 30%. I had also recently purchased the EcoFlow Dual Fuel Smart Generator (DFSG) and hooked it up to the D2M to give it a test, too. It came on right at the 30% mark I had set in the EcoFlow app. It took about an hour to charge the battery with propane. The generator then shut itself off automatically when the battery was fully charged. Dinner was served and power eventually came back on a few hours later. Both the D2M and the DFSG performed as expected with no problems. I highly recommend this set up. Before I would have to run my gasoline generator continuously during an outage. Even though it has an ECO mode, it would still burn 3-4 gallons per day. With the DFSG and a Smart Extra Battery (SEB) I will likely only need to run the generator 2-3 hours per day, and that can be reduced with solar panels. NOTE: I prepared for this EcoFlow setup by drilling a hole in my exterior wall. This allows me to keep the D2M and SEB inside but connect them to the generator, transfer switch, and solar panels outside. The PVC conduit has caps when not in use.

I'll give the 110w 5 stars based on my Brother's 130W he bought. We both used the 130W panel sharing it back and forth over a 4 day weekend. We charged his EcoFlow River Max battery and my Domtic PLB40 battery. We had our respective jumpers/adaptors to connect our respective batteries alternating every other day to the 130W solar panel. We used an aftermarket 10 ft solar extension cord from Amazon and it as a huge help. I suggest getting 20 feet. It worked great! As for the 130W ...We both were going from 30% power to 90% power in 3-5 hours. We were using 40 and 50 liter capacity refrigerators in 90+ temps during the day and 65 degrees at night. It was sunny the entire time (Grand Junction CO) . We did not reposition the panel. We just tossed it on the roof of the pop-up. Super easy to use, compact and a great value. I'm expecting the same with the 110w. If any solar panel lasts longer than 5 years of overlanding I'll be happy, I do think the 1 year warranty is nice but requiring me to keep the original box is stupid should I need to send it back for a warrant issue.

Easy to carry. Easy to set up. Easy to connect Works great

Best in class features, power and most importantly expandability!

I bought it about a month ago and it works like a charm

Awesome Light and quick. Easy to store cables are a good length

Great solar panels. I was surprised how well it charged.

I can't wait to use these products in my future Topper Camper!
